Senna was married to Lilian de Vasconcelos Souza from 1981 until 1982.
Though he did not have much of an income early in his racing career, Senna insisted on supporting his wife with no help from his father out of a sense of pride. The marriage ended in divorce.
Senna then courted Adriane Yamin, daughter of an entrepreneur from São Paulo, who was 15 years old when they began the relationship in 1985 and often chaperoned by her mother.
They were briefly engaged, but the relationship was broken off by Senna in late 1988.
Senna dated Brazilian TV star Xuxa from late 1988 until 1990. He then dated Christine Ferracciu, who lived with him at his homes in Monaco and Portugal, on and off between 1990 and 1991.
Senna also had an affair with American model Carol Alt, and briefly dated models Marjorie Andrade and Elle Macpherson.
At the time of his death, Senna was in a relationship with Brazilian model, and later TV personality, Adriane Galisteu.
Towards the end of his career, Senna became increasingly preoccupied with the dangers of his profession.
On the morning of his death, he initiated the reformation of the GPDA safety organisation, with which he had intended to work to improve the safety of his sport.
Just because I believe in God, just because I have faith in God, it does not mean that I am immune. It does not mean that I am immortal.
The harder I push, the more I find within myself. I am always looking for the next step, a different world to go into, areas where I have not been before.
It is lonely driving a Grand Prix car, but very absorbing. I have experienced new sensations, and I want more. That is my excitement, my motivation.
When TV interviewer pointed out to Michael Schumacher that his victory in the Italian Grand Prix in September was the 42nd of his career, surpassing the number of wins earned by the late Ayrton Senna, the German driver broke down and cried.
For the first time, the World saw the human side of the icy Schumacher.
The two of them where there in that cursed day back in 1994. Mika was his teammate for some races in 1993 and he knew Senna well.
And Michael was living his dream by having one of his favorite drivers as his main title rival.
These days in Imola have changed everything we know about Formula 1 and bring tears to the eyes of everyone who loves the sport.
